Mailman delivered four CNSunway 5000K 2400LM LED bulbs a few minutes ago. Snuck off of work and installed them (<5 minutes since I had done bypass yesterday which only took a couple of minutes). The work fine and I have light over the bench again!
Interesting difference is that you can see the tubes through the diffuser in the fixtures since the arrangement is not longer using the reflectors in the fixture. Light is good over bench. I'm please with the replacements.

Seems not everyone agrees with you, thus my suggestion, this quote from Regency Lighting who may just be overly conservative to avoid potential liability. https://insights.regencylighting.com...g-on-a-fixture
"We hope that once you retrofit to LED you don't decide to go back to fluorescent, but it's possible that someone could inadvertently install a linear fluorescent lamp in a ballast-bypass fixture. When the LED lamp does need replacing, if you mistakenly try to replace it with a fluorescent, the lamp may not work or could be hazardous."
There's also an posting on Quora that says it will explode but I don't know the credibility of that source.
Can't hurt to label it. In Canada you violate the CSA rating of the fixture if you bypass the ballast and to be legal you need to recertify the modified fixture so it's just not practical to do.
Either replace the fixtures with LED fixtures or remove the ballasts and go with bypass LED bulbs. Look on 1000Bulbs.com and you can get good pricing buying by the case (12 bulbs). Or check with your local electric provider, many have low priced LED bulb incentives.
NOW you tell me...
For future. How high is garage ceiling? if you are 10' or above 2 of these per bay absolutely fills garage Im 11' with 4 of these in 4 car garage

I had contemplated using some high bay LEDs to replace, but it was a bit cheaper just to use the bypass T8 LED tubes. The four tube 4 ft T8 fixture is getting close to the Lumen output in the one you spec'd (maybe a little off). The four ft four bulb fixtures with 2800 Lumen fluorescent tubes would be about 11200 Lumens. With teh CNSUNWAYs that I got at 2400 Lumen each will be about 9600 lumen. Comparing to some of the other fixtures (still with fluorescent tubes) the LED seems brighter than the first batch (but those were 4000K) and about the same as the last one I put in (I think 5000K). The LEDs are fine. And I did label with a sharpie LED only Ballast removed. When I can dig out my label maker I'll make a nicer warning label.

Where I live you cannot remove the ballast from the fixture and convert to LED's.
The fixture was designed with the ballast in place as the overload protection device, removing it removes the electrical approval.
I converted some of my fixtures to LED type, ballasts are the electronic type for T8 lamps....Rod.
